Description

  The present invention relates to a coral aquaculture structure for implanting coral larvae, in particular, a three-dimensional structure for coral aquaculture constructed by assembling a lattice structure, and a connector used to connect the lattice structure. About.

Coral reefs contribute to environmental conservation in coastal waters and play an important role in the protection and development of marine resources. Is an urgent need. Various attempts have also been made to create coral reefs from the viewpoint of coral reef protection. For example, a net made of steel, resin or chemical fiber is attached to a frame, and a reef-forming coral is fixed to the net with a wire or the like to increase the culture of the coral (Patent Document 1). In this state, there is a structure in which coral larvae are deposited and grown in this state (Patent Document 2). A lattice-like structure has also been proposed as a device that promotes the growth of spores and larvae such as seaweed and sponge animals (Patent Document 3).

  It is said that coral larvae swim using cilia, land on the adherent base, transform into a polyp, and gradually grow to increase the polyp. According to the report, coral larvae tend to land in dark places rather than in direct sunlight, and it is said that places with currents are easier to land.

  Coral larvae will land in places where there are tidal currents and shades, where the bottom of the sea is not a coral breeding base such as sand or coral gravel, or where gravel moves even if it is rocky. I can't grow up.

  In the known net-like structure described above, if there is a tidal current, the tidal current can flow through the mesh even if it is arranged in multiple stages, and the sea floor is not a coral breeding base such as sandy land or coral gravel. Although coral larvae can be implanted, it is considered that the coral larvae are less likely to be implanted when exposed to the sun. The net-like structure and the relatively troublesome work of attaching the net to the frame is necessary.

  On the other hand, the grid-like aquaculture device can be integrally molded and is thicker than the net-like structure, so it tends to be shaded. However, when it is submerged from the work boat, it lays down and lands on the seabed. However, if the seabed is sandy, some or all of it is buried in gravel, and even if the seabed is bedrock, there is little or no flow of seawater. It becomes difficult to land on the floor.

  In order to improve the above points, the present applicant previously proposed a three-dimensional structure for coral aquaculture in Japanese Patent Application No. 2007-248903. According to this structure, the area of coral larvae can be increased, the coral larvae can be easily settled, and the edge of the structure contacts the seabed just by sinking to the seafloor from the work boat. The structure supported by the seabed can be in a state where part of the structure is in contact with the seabed and other parts and other structures are raised from the seabed. Seawater can be moved through the structure, and when the sun goes in, the shade of the grid structure is likely to be shaded by the grid structure, and the coral larvae that have entered the structure enter the four-way frame. The coral larvae that float on the tide flow are more likely to land because they are surrounded and less likely to dissipate, especially when the surface of the pier is rough or uneven, making it easier for the coral larvae to land, Coral breeding base such as sand and coral gravel It is possible to reclaim coral larvae and reclaim coral larvae even in places where there is no rock or even where rocks and gravel move due to the flow of tide and coral larvae do not grow up That is, the structure can be easily manufactured by integral molding.
